BARREL-HOIST.

Application filed February 21, 1916.

To all whom it may concern Be it known that I, JAMES A. MCMASTER, acitizen of the United States, and resident of Kittanning, in the countyof Armstrong and State of Pennsylvania, have invented a new and usefulImprovement in Barrel- Hoists; and I do hereby declare the following tobe a full, clear, and exact description thereof.

My invention relates to barrel jacks, and its object is to provide ajack of substantial structure in simple form, capable of supporting afull barrel and holding same 1n non-tiltable position.

Other objects are, convenience in loading the jack and collapsing sameinto a small area for shipping or storing.

This type of jack :is adapted for use mainly in automobile garages, andis constructed to support gasolene and oil barrels in substantiallyhorizontal position, and at a height from the floor convenient for thewithdrawal of the contents.

In the accompanying drawings, Figure 1 is a perspective view of myimproved barrel jack in position for support of a barrel, the barrelbeing omitted so that all parts of the jack are seen; Fig. 2 is a likeView showing the jack folded for ship-ping or storing; Fig. 3 is a sideelevational view of the jack in position for receiving a barrel; Fig. 4.is a like view of the jack supporting a barrel and holding same againsttilting or rolling.

In the drawing the numeral 2 designates a truck frame forming a suitablebase to which the barrel member is connected. This frame is preferablymade of metal in the triangular form, as shown, and comprises the tworear branch members 3, provided with wheels 1, and a front branch member5, having the caster wheels 6, means, such as the U-bolt 5 beingprovided on the front branch for attaching a handle or other means formoving the truck. The triangular branch form of truck frame shown givesgreat stability to the barrel with minimum material to the truck frame,the branching arrangement permitting the standard and barrel support tolie between these mem bers when the jack is folded.

Connected to the truck frame by a standard 7 is the barrel supportingmember 8, this member is preferably made into the form of a fork havingthe prong-like arms 9 for engagement with the side of the barrel,

and the tang portion 10 terminating in a shoulder or lug 11 forengagement with the end of the barrel. This member is connected to thestandard at a point near the junction of the prongs by suitable pivotconnection 12, such as the cars 13, and bolt 14:. Similar pivot meanscomprising the ears 15 and bolt 16 connect the standard to the truckframe near the junction of the two rear branch members.

By referring to Fig. 4 it will be observed that the pivot connections ofthe standard to the barrel member and to the truck frame are so disposedin respect to one another as to cause the standard to lie in an obliqueplane when the barrel member and truck frame are in a substantiallyhorizontal plane, or when the jack is in supporting position. Thestandard is provided with the foot 17 engaging the barrel member andpreventing downward tilting of the front of this member, a movable stopmember 18, also secured to the standard prevents clownward tilting ofthe rear end of the barrel member, and similar stop members 19 and 20are secured to the lower end of the standard to hold and lock thestandard in in clined position, these members engaging a shoulder orseat on the truck. By this arrangement, it is obvious that with thebarrel member so proportioned as to bring the center of the barrel at ornear the connecting point 12 of the standard to the barrel member, thecenter of gravity of the barrel would be in advance of the pivotconnections between the standard and truck frame, and would act tomaintain the barrel in non tiltable position. To provide againstforcible tilting, the stop or looking member 20 is provided.

l/Vhen it is desired to load the jack, the stop member 20 is swung awayfrom its seat on the truck, and the barrel member and standard tilted inthe position as shown in Fig. 3, it will be observed that in thisposition the angle is very slight, and the barrel can be tilted againstthe barrel member without much effort, and by reason of the footengagement of the standard with this mem her, the jack is made rigid,the entire Weight of the barrel being on the jack members, and theweight being down, blocking of the wheels in loading is unnecessary.

To fold the jack, both stop members 18 and 20 are swung away from theirseats and we r..-

the barrel supporting member folded down to lie between the rear truckmembers as clearly shown in Fig. 2.

It will be noted, that my invention may be used in various forms ofconstruction of barrel member and truck frame, and other means forconnecting the barrel member to the truck could be employed and theseare intended to be within the scope of the claims.

WVhat I claim is:

1. A barrel jack comprising a truck frame, a barrel supporting member, apostlike standard, means for connecting the standard to the truck frameand supporting member, saidmeans being so disposed in respect to thecenter of gravity of the barrel as to cause the standard to maintain thebarrel in supported position.

2. A barrel jack comprising a truck frame, a barrel supporting member, aconnecting standard, pivotal, connections between the standard and the"truck frame and between said standard and the barrel supporting member,said pivotal connections being so disposed inrespect to one anotherwhereby the center of gravity of the barrel maintains the barrel insupported position.

3. In a barrel jack, the combination of a truck-frame, a barrelsupporting member, a pivoted standard connected to said barrelmember,'means for locking the barrel supporting member against tiltingon the standard, I and pivotal connections between the standard and saidtruck-frame, whereby the center of gravity of the barrel maintains thebarrel in supported position.

4. In a barrel jack, the combination of a truck frame, a barrelsupporting member, a standard, pivotal connections between said barrelsupporting member and said standard, means for locking said member onsaid standard, pivotal connections between said standard and said truckframe, said last named pivotal connections being so disposed in respectto said first pivotal connections, whereby the center of gravity of thebarrel supporting member acts to maintain said member in supportingposition, and positive locking means for locking said standard to saidtruck frame.

5-. In a barrel jack, the combination of a truck frame, a barrelsupporting member, a standard, pivotal connections between said barrelsupporting member and said standard, a locking member on said standard 5adapted for engagement with said barrel supporting member in supportingposition, pivotal connections between said standard and said truckframe, a second locking member on said standard adapted to engage saidtruck frame and hold said standard and said barrel supporting member innon-tiltable position.

6. In a barrel jack, the combination of a truck frame, a barrelsupporting member, a standard, pivotal connections between saidsupporting member and said standard, said member adapted to be foldeddown, a locking member pivoted on said standard, and adapted forengagement with said supporting member when in unfolded position,pivotal connections between said standard and said truck frame, a secondlocking member pivoted to said standard and adapted to engage said truckframe to hold said standard in upright position, and to be swung out ofengagement with said truck frame to permit the folding down of saidstandard.

In testimony whereof, I the said JAMEs A. MGMASTER, have hereunto set myhand.
